During normal operation, minstrel was showing suspicious EWMA probabilities
exceeding 100%. It looks like the tx status reporting in ath5k was not
properly clearing the rate index for rates which were never attempted.
This is caused by uninitialized stale data in the on-stack tx status
information, which is reused when more frames are received.
To fix this, rely on ts->ts_final_idx to select the last attempted rate,
instead of checking whether ts->ts_rate is set.
Additionally, the conversion from the driver rate index back to the
mac80211 rate index can be dropped, as the mac80211 tx status will still
have the original rate index which was used to set up the descriptor.
Additionally, one more inaccuracy was fixed - the final rate attempt
count only needs to be increased by one if the transmission attempt was
successful.

The problem is that when the attenuation is increased,
the rate will start to drop from MCS7 -> MCS6, and finally
will see MCS1 -> CCK_11Mbps. When the rate is changed b/w
CCK and OFDM, it will use register desired_scale to calculate
how much tx gain need to change.
The output power with the same tx gain for CCK and OFDM modulated
signals are different. This difference is constant for AR9280
but not AR9285/AR9271. It has different PA architecture
a constant. So it should be calibrated against this PA
characteristic.
The driver has to read the calibrated values from EEPROM and set

There's no need to keep both normal and BT statistics

Also, in doing so, we can remove all the calls to

access the copied statistics now.
Finally, also remove this call from the one place
where it might still be needed and automatically
detect what kind of statistics the device is sending
based on their size. This way, we don't need to keep
track of which devices do what any more, which is
good since this is subject to change based on the
ucode version (as some ucode even for non-BT devices
will in fact use BT statistics).
